Square 1:1 typographic key-art poster, designed as a Y2K holographic sticker composition. Deep purple-black background with a subtle radial fade, faint scanline texture, diagonal prismatic light streaks, and sparse tiny holographic star stickers. Center a single enormous uppercase letter “S”, occupying 68% of canvas height. The “S” is custom bold geometric lettering with wide, flat, rounded stroke faces and tight smooth curves; made from thick premium metallized holographic foil. Across every face, show fine parallel diffraction-grating lines, angular viewing-angle color zones shifting gold, cyan, hot pink, electric purple and violet; razor-thin rainbow fringe around the outer contour; one bright white specular reflection line following the center of each major stroke. Add crisp four-point starburst sparkles at three letter edges and a soft magenta-cyan reflected glow onto the background, without obscuring the silhouette. Typography hierarchy, all text exact and highly legible: at top center, small spaced uppercase “SIGNAL / 2026” in clean condensed white sans lettering. Main centerpiece: “S”. At bottom center, “STUDIO SERIES” in small uppercase cyan-white geometric sans; beneath it, tiny “ONE LETTER. FULL SPECTRUM.” in pale lavender. Maintain generous margins, exact spelling, no extra words, no people, no objects, no logos. Front-facing graphic poster, controlled foil highlights, sharp print-like edges, high-resolution render.
